What's the matter with the wrong engine number?

An incorrect engine number may be due to incomplete input of the engine number. You can try using the vehicle identification number (VIN) instead. Contents included in the engine number: The sequence and contents of the engine number vary by manufacturer. Generally, it includes the engine model, production date, and a randomly assigned serial number when the engine comes off the production line. Some may also include a production location code. Uniqueness of the engine number: The uniqueness of the engine number is also to ensure traceability, making it easier to track and obtain feedback when issues are found with the engine or when the manufacturer conducts investigations.

Last time when I was handling the vehicle transfer at the DMV, I encountered an issue with the engine number mismatch. The staff checked it several times using the rubbing paper. They explained that common causes include: the factory engraving being too shallow resulting in blurred rubbing, oil contamination during vehicle use, or failure to re-engrave the number after engine replacement by repair shops. In my case, the stamped number on the engine block was covered by oil sludge, and only became visible after spraying and wiping with carburetor cleaner. I suggest first carefully cleaning the engine number location. If there's still a mismatch, immediately go to the DMV for registration, otherwise it may affect annual inspections or even raise suspicion of the vehicle being stolen. Illegally altering an engine number is a criminal offense - never attempt to handle it improperly yourself.

Having repaired cars for over a decade, I've encountered numerous cases of mismatched engine numbers. The most common scenarios are rusted numbers due to water ingress in the engine bay, or forgotten re-registration after engine replacement following an accident. Last month, a car owner discovered mismatched numbers, which turned out to be due to the previous owner's involvement with smuggled and reassembled vehicles. If you encounter this situation, don't panic. First, use your phone to clearly photograph the engine block's engraved number location and compare it with the vehicle registration certificate photo. If there's indeed a discrepancy, immediately contact the DMV to process a modification registration. You'll need to bring supporting documents such as the purchase invoice and repair receipts. They will conduct a vehicle inspection and update the records, typically completing the process within two to three days.

The engine number is like the vehicle's ID card, where every stamped letter and digit must be correct. I noticed that my neighbor's new car had an incorrect engine number registered. The 4S store explained that the cylinder block was deformed due to impact during unloading in transit, and the number became distorted after re-welding. They provided a manufacturer's certificate to complete the information correction. When transferring ownership or claiming accident insurance, staff will carefully verify this number. For older vehicles, it's advisable to clean the oil stains in the number area in advance to avoid issues during annual inspections.
